Is an INFP 4w5 sx/sp odd? or actually common. I know the enneagram part is but the instinctual?
it seems to kind of make everything more extreme or something.

I'm really wacky, and I've noticed most infp's on these messageboards seem sp/sx's, but sx/sp seems to be a bit more rare.
While the enneagram and MBTI description helped me understand myself the instinctual really helped also in filling in some gaps that were kind of missing a bit.
I really do feel like the embodiement of a tortued artist and times and it's kind of ridculous. Like i'm a giant cliche. I've tried medication but they always have too many side effects. My moods are just insane sometimes, yet I always feel this need for intensity. But it's better for me to have intensity then mediocrity because it feels far worse then depression, haha.

INFP is one of the common among 4w5s Sx/Sp. Maybe INFJ too, but less likely.

Also, I'm searching for an IFP 8. Seem like truly at odd or even impossible.

Is ESFP e9 sx odd? She's very in the moment, but works to make the moment cheerful. She's pretty sociable but has an energy limit, and she procrastinates like no one else. She isn't forceful and she doesn't wear her heart on her sleeve like other Se-doms I've known.

I'm an INFP 6w5 so/sx, and I think my tritype is 621. INFPs are stereotyped as 4s or 9s, but I do not related to the "I am a special snowflake" fixation of the 4 or the doormat-like, compartmentalizing, and dissociating quality of the 9. Anxiety and fear of being without support is my core neurosis.
